H/C/I Question

Just go ahead an run it with your H/C/I and if something goes wrong just rebuild it later...by the way what kind of combo you thinking about?

I would say that as long as the car's not burning oil and a compression test looks good, then go ahead with putting the H/C/I on the stock shortblock.

I say the same. just go for it.

Do a compression check on the engine. If it's all good, then go for it. If not, then rebuild time.

To make power naturally aspirated, you almost always have to raise the power band of the engine. Most performance head, intake, cam combos that will put you in the 300+ rwhp range will push the power band up to at least 5500-6000 RPM. For a street car, you generally won't be able to take advantage of this unless you've got the rear end geared for it and you regularly "beat" on the car. If it's a race car, then go for it. That said, the stock bottom end will likely have its life shortened.

If this is primarily a street car and the compression is good, then I would go with a 6-9psi street blower. You'll have the off-idle grunt and at least as much power, but without needing see 5000+ RPM. With good, safe, conservative tune you should be able to make 300 rwhp on pump gas and not necessarily put any undo strain on the engine.

With my combo, it feels pretty stock below 2500 RPM. It isn't until it's singing around 4000-5000 RPM that it really gets fun. Most folks with street cars like to feel that power immediately off-idle at stoplights and such,...mine...not at all. Something to think about.

Good luck with whatever decision you make.

i was thinking about the trick flow power package, or even the edelbrock combo, but im still not sure. its not gonna be a drag machine so i want something that will give me power right from the start

only thing that would give you power from the start is more cubes or a roots type blower. that and/or gears or atleast it'll "feel" that way.

i am running gt40/stock ported heads/cam (unknown until monday havent taken it out to check). My setup pulls from 3,000 up , and lowend torque is pretty good. Cam is everything, you need to figure out if you want a cam setup for street (torque maxed out as soon as possible and hp follows), or , "race track" cam (which is pretty much, the higher you spin the engine the more power you get) I am more of the street car cam guy, this is becuase i love to feel that torque down low. Its all in what you want

I did the FTI combo on my stock 80k bottom end and made 303rwhp untuned. Car ran great and still got 20+ mpg depending on how I drove. Not concerned about bottom end. Like above mentioned, as long as compression is good, go for it. Check out www.flowtechinduction.com for some ideas of fast stock bottom ended combos.
